Niiiiiiice! Looks like effectively the same thing as the Jeepsterman setup (def. the same switch), only I'm guessing it cost MAYBE half what mine did 😂

OK finally found my grinding noise I've been chasing for awhile. Wheel bearing/brake bracket was not it.

Turns out the shift linkage for the D20 wasn't in great shape, and was allowing it to try and enter 4 hi, which at 60 mph with the hubs unlocked...means the front isn't even spinning. Also it was full of transmission fluid, leading me to believe that the input seal died and allowed transmission fluid into the case.

The deal is, I get a week to figure out a 700r4/np 208 or 241. We figured since the tcase was out anyway, like half the work is done for a 700r4. If I don't get something figured out by then, I'll order the stuff for the D20 and rebuild it, and put it all back together.

Fingers crossed I find a 700r4

Yikes, big task, but a 4th gear will make it worth it. I’m a big fan of the NP241, the full time and part time 4wd is a really nice option to have. A little less heavy duty than a 208 I think but I had a stock one turning 37’s up rocks and stuff so it’s definitely good enough… plentiful enough in Jeeps too

If I've done my reading right, the 241 is a 208 with better oiling and such. Not the same as the 241 in the Rubicons--I think the one I'm looking at is technically a 241C.

Not having much luck there; it's unfortunately looking like I'm gonna end up rebuilding the D20 and leaving the turbo 400. I hate that...I was really hoping I could stand a chance of pushing 20 mpg.

Sierra, you need to find that guy in IA that modified his old Maverick 302 with a lawnmower carb, and got over 40+ mpg on his test run.
Younger guy not much older than yourself, but knows what the heck he is doing.
Saw it on youtube.

Yeah I've seen that too. Trouble is I highly doubt a lawn tractor carb would have enough flow for 60 mph pushing a barn door through the air lol.

Small update; I found the source of my noises. Intermediate shaft--if you spin it, most of the time it's fine, but if you spin it JUST right, it makes a terrible grinding noise. Looking at the shifter I'm not really sure it's actually worn out.

Lots of tranny fluid in it, which would be fine with a manual just not with my TH400. New adapter seals and bearing, as well as all new bearings and seals all throughout the tcase.

What do you guys recommend for oil in it? Initially I was thinking synthetic to be thinner in the cold, and better heat dissipation in the hot. And hey, more slippy slidey means better mileage right? ;)

Anyway, stock Dana 20 rebuild, any tips would be appreciated. Planning to order the rebuild kit tonight.

Looking forward to getting to drive it again!

Well, made it 14 hours out to college in the Jeep, loaded down with all my stuff. All it needed was gas and oil, and a little persuasion at high altitude to start when hot.

One pic is in the driveway ready to go, and the other is up over 10k feet. It actually hit over 12k feet at one point, and still had more power than our '95 4.0 ZJ.

My voltage regulator gave out in the parking lot, so I guess I get to install a 1-wire alternator in the parking lot this week :lol:

I would caution against a 1-wire alternator on anything. However I would strongly advocate replacing the Motorola with a Delco 10SI or 12SI which eliminates the external voltage regulator. Why Jeep didn't use a GM alternator on GM engines is a mystery. They probably had a warehouse full of them and a contract to buy more.

I put a 12 SI on my 71 about 20 years ago and never looked back. Just run the "sense" (2) wire to the large binding post on the starter where all of the loads are bussed. The original wire from the dash lamp, mine was grey IIRC goes to the (1) terminal.

1 wire really isn’t the right term. He’s putting a 12si in. I’m helping him wire it up so it’s mostly a 1 wire lol. That is if the field energizes without the exiter wire, most of them will but some will not. In my experience it’s luck of the draw.

Thank you for this. I didn't hook up that dash wire initially and had some issues. Now it just needs a jump and should be good to go again--just need to actually do that. I'm optimistic though, and this alternator cleans up the stuff under the hood so much, it's really nice.

Thank you for your help too, Yeller. Just needed to hook up one more wire from where I was lol.

Just got back from a spin in the Jeep since I swapped the alternator, and hooked up the white wire. After a jump, everything works as it should and it starts all on its own; 12V idling with almost everything on, and like 13-13.5V driving, also with most stuff on. Should be good to go for awhile. I may swap it to a Vortec starter at some point, we'll see. For now it's charging and starting on its own again.

Battery was so dead that it darn near stalled my friend's Forester when I cranked mine. Gave it a couple minutes to charge up and it didn't have any problems. This morning I had some errands to run and it started just fine for those too. It looks so much cleaner with that alternator too...and the voltage is so much more stable. Wish I'd done this swap a long time ago.

Now to figure out how to wash it... :lol:

Lol.

My friends have talked me into taking it to cars and coffee next month...after all the fun in the mud and everything it needs cleaned first, BADLY...
